PATENT Aor-rlca JOSEPH W. BISHOP, OF MUSKEGON HEIGHTS, MICHIGAN, ASSIGNOR TO THE BRUNS- WICK-BALKE-COLLENDER DELAWARE l COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF TOILET SEAT Application led April 13,

My invention relates to toilet seats, and more particularly to devices for securing hinges thereto. f

Toilet seats have long been constructed with the hinge lugs screwed directl into the wood. This construction is unsatis actory as it permits 4moisture to get in around the screws, causing the loosening of the screws and resulting in an unsanitary and insecure connection. v,

One object of the invention is to provide a toilet seat member composed of plastic com position which extends about a hinge element having projecting hinge members, the plastic composition extending continuously over the hinge members so as to prevent moisture from entering the seat or attacking the hinge members. v v

A further object of the invention is to provide means for so securin to a toilet seat a hinge lug having a lateray disposed pintle that it will be impossible for the lug to twist to the seat.

A stil further object of the invention is to provide a rubber coated segmental check or stop hinge pintle for toilet seats which will be inexpensive to manufacture and will t accurately in the socket of a supporting standard.

Other objects and advantages will appear in the course of the description.

Referring to thedrawings, forming a part of this specification,

Fig. 1 represents a plan view, partly in section of a seat embodying my invention.

Fig. 2 is an elevation view, partly in section2 taken on line 2-2 of Fig. 1.

Fig. 3 is a sectional view taken on line 3--3 of Fig. 1.

Fig. 4 is a sectional view taken on line 4 4 of Fig. 2.

5 is a sectional view taken on line 5--5 of Fig. 1, and

Fig. 6 is a sectional view similar to Fig. 5,v

showing a modified form of my invention.

The form of my invention shown in Fig. 1

ceive it, is the metallic insert 2, which may be 1928. Serial No. 269,736.

a malleable iron casting or made of other suitable metal. The insert is preferably formed with corrugations or ribs on its surtion, such as hard rubber, a phenolic conden- -sation product,-nitrocellulose, etc., coversfthe core and extends outwardly from the core and uninterruptedly over the hinge lugs, thereby lforming a continuous surface extending outwardly from the core, closing the joints between the core and lugs and, since the coatin is of substantial thickness and has consi erable inherent strength, effectively assisting to maintain the lugs rigid with the seat.

The coating preferably is extended over the pintles 5,. This is an important Vfeature of the construction, since due to the `fact that the coating is applied by a molding operation, the pintles will in this operation be formed to-uniform sizes for cooperation with the complemental hinge parts. Thus, the necessity or accurate machining of-the metal is eliminated, anda hard smooth hinge surface is ,providedin the molding operation.

In constructing the seat, the insert 2 is driven into the rear of the core, as stated above. 4If it is desired that the coating should be of rubber, a layer ofrubber 7 is then applied so as completely to cover the core, the lugs and the pintles and is vulcanized thereto forming a hard coating, which unites the hinge parts with the core into an exteriorly integral structure devoid Vof surface joints or cracks, and materially reinforces the attachment of the hinge parts to the seat.

A standard 8 is provided for each pintle, having a socket 10, which is circular in cross section except for a sectoral abutment 11,

occupying slightly less than a quadrant in the socket 10, for limiting the movement of the pintle when the seat is rotated slightly beyond a vertical position.

The standards 8 also preferably have a coating 12 of plastic material similar to the coating described, over their entire exterior surface, as shown in Figs. 2 and 3.

It will be seen that I have provi-ded an extremely sanitary toilet seat. Since the seat and hinge are completely covered with rubber, no metal surface is exposed, and there is, therefore, no possibility of admission of moisture or dirt within the core. Aside from its sanitary features, an unusually rigid structure is provided by having the hinge lugs integral with the metallic insert, thus eliminating the loose connections usually found in seat hinges of this type.

In the modification lshown in Fig. 6, the core 13 may be made of ground cork, or of wood shavings or sawdust held together by a suitable binder, or it may be made of a cheaper grade of hard rubber, theiseat being composed entirely of a plastic composition and having an insert 14 similar to the insert 2 embedded therein.

My invention is not limited to the specific details of the embodiment shown and described, but changes may be made in these constructions without departing from the spirit of the inventions While my invention is shown in connection with a vseat strictly so called, it is to be understood that it is equally applicable to the cover which forms a part of a seat, and the word seat as used in the accompanying claims is used in its broader sense.

I claim 1. A toilet seat composed 'of plastic composition, an insert enclosed by said seat and extending transversely thereof, an outwardly projecting hinge member integral with said insert, said plastic composition extending about said insert and outwardly over said hinge member and presenting an unbroken surface at the points of juncture of said hinge member and said seat, and standards supporting said hinge member for pivotal movement.

2. The combination with a toilet seat comprisingV a core and a coating of plastic composition about said core, of an insert enclosed within said coating, a pair of hinge members rigid with said insert and projecting outwardly from said seat, said coating extending uninterruptedly from said core outwardly over said hinge members, and standards supporting said hinge members for pivotal movement.

3. The combination with a toilet seat comprising a core and a coating of plastic composition thereon, of an insert embedded in said core and'having a pair of hinge lugs thereon extending outwardly therefrom, said coating extending uninterruptedly from said core outwardly over said lugs, and standards supporting said hinge members for pivotal movement.

4. The combination with a toilet seat, of a hinge lug secured thereto, a segmental pintle integral with said lug, a coating of a plastic composition over said lug and said pintle, and a standard having a socket therein for receiving said pintle, and an abutment in said socket for limiting the rotation of said pintle.

5. A toilet seat composed of a plastic composition, an insert-enclosed by said seat having a hinge lug integral therewith, said lug having a laterally disposed pintle, the plastic composition of said seat extending uninterruptedly over said lug and pintle, and a standard supporting said pintle for pivotal movement. l

6. In atoilet seat, a core, a metallic insert embedded in said core, metallic hinge lugs integral with said insert and projecting from said core, and having laterally disposed pintles of segmental cross section, said core and projecting lugs being coated with hard composition extending uninterruptedly from said core outwardly over said lugs, anda pair of standards, each having a socket therein .for receiving one of said pintles, and an abutment in each of said sockets for limiting the movement of said pintles.
